"All three engines being nearly the same size305,301,292 it should be dooable,right?"
Yep its quite easy. Get a HEI dist. for the ignition this way you can control the timing as well as the fuel.
I suggest getting the truck running with the stock 292 first then convert to EFI ( install the EFI tank, pump, and fuel lines and use a holley bypass regulator to feed the stock carb) then add the turbo. A little planing will ease the upgrades. This way you can test and sort out issues as you go. The only kink with this approach is the TV cable for the 700R4. When you get closer to installing the harness let me know and we work through it.
